kafka-python-docker-example's Introduction

kafka-python-docker-example

Experiment project with Docker, Docker Compose, Python and Kafka. The pipeline is:

(HTTP POST) => Endpoint => Kafka (Raw data topic) => Parser => Kafka (Parsed data topic) => Persister

Currently we are just passing the same message from the HTTP POST request all the way to the end of the pipeline.

Requirements

  • Docker (and Docker Compose)

Setup & Run

$ git clone [email protected]:pjlampil/kafka-python-docker-example.git
$ cd kafka-python-docker-example
$ docker-compose up

Run migrations

$ docker-compose exec api ./manage.py migrate

Usage

Following command will send a message (with somewhat random value) every two seconds until quit. It sends a HTTP POST to the endpoint to simulate the real world scenario.

$ docker-compose exec persister ./manage.py send_messages 2

API

API can be found by default from http://localhost:8001/observations

Example Frontend

An example frontend that uses API and visualizes the data can be found by default from http://localhost:8002/
